DAC chip capable of MQA decode is a very recent thing. Before 9068 this did not exist.i tried to find out what exact Burr Brown DAC chip model is used in this new Neo iDSD, but unfortunately, nowhere is this information given!
i wonder why?
for DAC chips in these DAC decoders made by many manufacturers, it's like buying a laptop or a PC - the more current the DAC chip inside, the more likely that for the same amount of money, you get greater performance and the unit is more future proof (for a few years). yet, i can't find which Burr Brown DAC chip is inside this Neo iDSD. i wonder why?
also: it says that the Burr Brown AND the 16-core XMOS is doing a lot of the MQA decoding work, emphasis on the 16-core XMOS.
i'm wondering if the 16-core XMOS doing the MQA decoding is considered "full hardware MQA full unfolding"? or is it software unfolding? i had previously thought that FULL HARDWARE MQA UNFOLDING means that the DAC chip has built-in capabilities of doing full hardware unfolding, like the ESS 9068 chips inside the Astell and Kern Kann Alpha. here, it seems very opaque as to how much of the unfolding is done and if it's FULL MQA unfolding or merely partial?
any information or education on this would be most appreciated. thank you all in advance. it seems quite confusing to me!
The chip has multiple channels, so it is likely still balanced.

It is always, and has always been, DSD1793 chip from burr brown... no secret...Thanks for the thoughts re: the Burr Brown DAC and the MQA on this Neo iDSD, guys.
Here's what i dug up on iFi's company literature, which has nothing, NOTHING at all, on the Burr Brown DAC chip's model number. very odd. anyone else using, say, the ESS 9038 or ESS 9078 (like my Kann Alpha) would list the DAC chip prominently!

- MQA (Master Quality Authenticated) is supported through the USB and S/PDIF inputs, with full decoding of MQA files up to 384kHz thanks to the processing power of the new 16-core XMOS chip.
This means that the full ‘three unfold’ decoding process is performed internally, as opposed to only the final unfold in the manner of an MQA ‘renderer’.
Globally, MQA has become an important consideration for any comprehensively equipped DAC. It is available through for Tidal Masters, Audirvana and Roon.- The Burr-Brown True Native® chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded.
At iFi we use Burr Brown extensively in our products having selected it for its natural-sounding ‘musicality’ and True Native architecture. Our experience with this IC means we know how to make the most of it.- The XMOS 16-Core chip processes the audio data received via the USB and S/PDIF digital inputs.
This new low-latency XMOS microcontroller has greatly enhanced processing power. Compared to the current generation of eight-core chips, this new 16-core IC delivers double the clock speed (2000MIPS) and four times the memory (512KB), as well as the latest SuperSpeed USB standard.
iFi’s in-house digital development team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the Burr-Brown DAC.- Hi-res audio support is state-of-the-art with True Native® playback. It handles PCM data to 32-bit/768kHz, DSD up to DSD512 and single and double speed DXD.
Thanks to the Burr-Brown DAC chip’s four-channel True Native design, PCM and DSD take separate pathways – this enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through to analogue conversion. This is not the case with all DAC devices from other brands – even if DSD compatibility is stated, many such DACs convert DSD signals to PCM.
@Baten: thanks for your chip model info.
if that's indeed the chip in the Neo iDSD, then this DSD 1793 chip is from 2003!!! please see:
https://www.ti.com/product/DSD1793
scroll down to the Data Sheet and the User Guide links for downloading those and, on the far right of those two links, are the dates. The user guide is from 2003!
Can that possibly be true? that this Neo iDSD uses a Burr Brown DAC chip from 2003?
very confused and bewildered...

It's all about what one can do with a chip, not the chip itself or how old it is
Guys, this stuff has been repeated over and over every time iFi releases a new dac/amp....
They chose this chip for its musicality over sheer specs or measurements.
And yes apparently the neo has 4 of them in interleaved configuration, so actually double as much as the iDSD micro BL
@iFi audio:
thanks for your comment.
while what you wrote is true, i'm just befuddled as to why one would choose to use a 2003 DAC chip? what is it that i'm missing in my head in trying to understand this please? i'm asking for educational purposes in my effort to understand this prior to making my purchase. i'm very tempted, as iFi's reputation for excellent products, especially in this DAC area, is well known, but this new revelation of a 2003 chip confuses me and is taking me for a spin!
granted, i fully realize that there is a XMOS 16-Core chip that works hand in hand with the Burr Brown DAC chip from 2003, true. still...wouldn't one think that by using a 2019 or 2020 DAC chip, instead of a 17-year DAC chip, you'd think that the combination of a 2019 or 2020 DAC chip PLUS the 16-core XMOS would be superior than a 2003 chip plus the XMOS, right?
